Casco Bay, Coastal bay in Maine, US.
Casco Bay spans along Maine's southern coast and contains numerous islands, rocky shores, and tidal marshes scattered throughout. The bay stretches between Portland and the Atlantic Ocean.
Native peoples occupied the bay region for generations before Europeans arrived in the early 1600s. The newcomers built maritime trade and fishing settlements that shaped the coastline for centuries.
Fishing remains woven into daily life, with local boats working these waters as they have for generations. Lighthouses dot the shoreline and serve as landmarks that connect people to maritime traditions.
Ferries run regularly from Portland to connect various islands within the bay. Visitors can also paddle kayaks, swim, or take guided boat tours to explore the waters and nearby islands.
The bay shelters a protected habitat where seals, seabirds, and marine creatures live among the islands and open water. This mosaic of undeveloped land and shoreline offers visitors chances to spot wildlife as they move through the area.
